在包括人类在内的各种脊椎动物的大脑解剖中发现了性别差异。常识告诉我们，大脑中的性别差异导致行为上的性别差异。这篇评论认为，大脑中的性别差异也可能起到完全相反的作用。具体来说，性别差异可能会让男性和女性表现出非常相似的行为，尽管他们的生理和荷尔蒙状况存在重大差异。首先，解释结构和功能之间的关系的困难将说明讨论的性二形内侧视前区（MPOA）在男性性行为和父母的行为中的作用。第二，大脑的性别双态加压素神经支配将作为一个系统，似乎促进以及防止行为的性别差异。最后，将讨论人类大脑性别差异的基础和临床方面。(C)1998 Elsevier Science B.V.保留所有权利。
Sex differences have been found in the anatomy of brains of a wide variety of vertebrates including humans. Common lore tells us that sex differences in the brain cause sex differences in behavior. This review entertains the possibility that sex differences in the brain may also do the exact opposite. Specifically, sex differences may allow males and females to display remarkably similar behaviors, despite major differences in their physiological and hormonal conditions. First, the difficulties in interpreting the relationship between structure and function will be illustrated by discussing the role of the sexually dimorphic medial preoptic area (MPOA) in male sexual behavior and parental behavior. Second, the sexually dimorphic vasopressin innervation of the brain will be presented as a system that appears to promote as well as prevent sex differences in behavior. Finally, basic and clinical aspects of sex differences in human brains will be discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
